There was a time before computers had a controller called a mouse. There was a time before personal mobile phones had touchscreens. There was a time before humans harnessed the power of electricity to enable them to control and interact with the world around them in ways that'd be otherwise impossible. Google has a concept for a device that might launch the next generation into the future as a singular controller for the operation of all things digitally connected. It's sort of like a magic wand, and it's called the House Mouse.
